@Robert613 Another thing you might want to think about is whether you want to provide the same level of amenities to a month-long guest as to a short-term one. Longer stays are often discounted as compared to short ones, so you don't want to end up with a guest who goes through 2 rolls of toilet paper and paper towels a day and is an all day coffee drinker who'll go through a pound of coffee every 3 days. And longer term guests tend to be home more than short term ones, who are often out and about, so they'll tend to go through more stuff.
Some hosts will give LT guests a "starter pack", so they don't have to run right out to the store- maybe enough for a week, then the guest is expected to supply their own. You can choose to keep providing everything you normally would for a short stay, it's just something to consider and to make clear in your listing info and when communicating with the guest at booking time.
